# Upgrading the firmware on Grandsteam phones

**To upgrade the firmware of Grandstream phones follow these steps:**

1. Find the IP address of the phone by either using an IP scanner tool or by pressing the up directional key on the phone.
2. Login to the phone's web interface (default login credentials are Admin Admin)
3. Navigate to the 'Maintenance' tab and click on 'Upgrade and Provisioning' in the drop-down menu.
4. In the page that opens enter one of the below links into the 'Firmware Server Path':
   *  For GXP2140 enter: [malab.grandstream.com/firmware/Color/1.0.7.25](http://malab.grandstream.com/firmware/Color/1.0.7.25)
   *  For any other model entering: [firmware.grandstream.com](http://firmware.grandstream.com/)
5. Now you can reboot the phone to start the upgrade process as it should check the server for new firmware on boot up.
   *  **Note:** If the reboot doesn't start the upgrade process you can try going into 'System' in the phone's menu and selecting 'Start Provision'.

The phone should now be upgraded to the latest version available from Grandstrea

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kb.hostednetwork.com.au/support/services/voice-over-ip-voip/technical-references/brand-specific-guides/grandstream-handsets/upgrading-the-firmware-on-grandsteam-phones.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
